NUT-LOCK.
SPECIFICATION forming part Of Letters Patent NO. 625,493, dated May 23, 1899.
Application filed March 18, 1899. Serial No. 709,605. (No model.)
To (tZZ whom it may concern:
Be it known that I, JOHN WALTER DUTY, a citizen of the United States, residing at Bearsville, in the county of Tyler and State of West Virginia,have invented a new and useful N ut- Lock, of which the followingis a specification.
This invention relates to nut-locks, and has for its object to provide a simple and efficient device for locking nuts against accidental displacement which may be readily applied and removed without altering the form of either the bolt or nut and without damaging or impairing the same.
To these ends the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims.
In the drawings, Figure 1 is a perspective view of a portion of a railway-rail joint having my improved nut-lock applied thereto. Fig. 2 is a vertical transverse sectional view taken through one of the bolts. Fig. 3 is a horizontal transverse sectional view. Fig. 4 is a detail perspective of a modified form of cap-plate. Fig. 5 is a longitudinal sectional view showing the modified plate applied in locked position. Fig. 6 is a face view showing the engagement of the plate with the nut. Fig. 7 is a detail perspective View of the locking-key.
Like numerals indicate like parts in all the figures of the drawings.
Referring to the accompanying drawings, 1 and 2 designate, respectively, opposite abutting rail-sections having the usual fish-plates 3 and connecting-bolts 4., whereby the railjoint is made secure. These parts of a railjoint are shown in the drawings to illustrate the application and operation of the device, so that the same may be more readily comprehended.
The invention consists, essentially, in a capplate 5, which is adapted to receive the nut and provided with a key 6, which is designed to prevent loss of the cap-plate longitudinally from the bolt or bolts. This cap-plate may be applicable to a plurality of bolts, as shown in Fig. 1, or to a single bolt, as indicated in Fig. 5, a description of which latter is deemed sufiicient, as the form shown in Fig. 1 cmbodies simply a plurality of the devices combined in asingle plate. Referring, therefore, particularly to Fig. 5, the plate is of suitable length, flat upon its inner face, and thickened or enlarged outwardly, as at 7, intermediate of its ends. This enlargement is provided with a transverse opening 8 for the reception of the bolt to which it may be applied, and the inner end of the opening, beginning at the inner face of the plate and extending inward a suitable distance, is enlarged, forming a socket or recess 9, which is adapted to inclose the nut. The general contour of this socket is circular, being concentric with the opening 8 and provided with the toothed or angular peripheral wall 10. It will be noted that the opening 8 is formed near one side of the enlargement, and the rear wall 11 of the 7c socket is partly cut away at one side of the opening by a vertical slot 12-, extending entirely through the enlargement from top to bottom and intersecting the opening at one side thereof.
In the application and operation of the capplate, as hereinbefore described, and shown in Figs. 1 and 2, the plate is positioned by receiving the nut end of the'bolt through the socket 9 and into the outer end of the opening 8, Where it is adapted to remain. The nut 13 is received within the socket,the toothed or angular peripheral wall 10 thereof being adapted to snugly embrace any shape of nut and turned at any angle, as will be understood. In this position the upper longitudinal edge of the capplate engages firmly againsttheunder side of the overhanging tread 14 of the rail, and the lower edge rests upon the flange thereof and the inner fiat face against the fisl1plate,where- 0 by the cap-plate is fixed, and as the nut 13 is positively connected to the plate by the embracing peripheral wall of the socket 9 the said nut is efiectively prevented from being turned.
To prevent the cap-plate from being displaced longitudinally from the bolt, a flat wedge-shaped key 6 is provided, being shown in detail in Fig. 7. This key has one longitudinal edge 16 beveled or tapered inwardly mo and downwardly from top to bottom, and the opposite edge 17 is sharpened, while the opposite flat faces converge downwardly.- Near the upper end of the key and in the edge 16 is provided a notch 18. WVhen the cap-plate has been fitted in place, as hereinbefore described, the key is inserted into the slot 12 from the upper end thereof, with its sharp edge next to the bolt, and is driven or forced downward until its lower end projects a suitable distance through the bottom of the slot and below the enlargement 7 of the cap-plate. By reason of the beveled edge 16 of the key engaging the wall of the slot the opposite sharp edge of the key is forced between the threads of the bolt, whereby the cap-plate is locked against longitudinal displacement, as will be understood. By reference to Fig. 3 it will be seen that the wedge-shaped key is also wedged against the outer face of the nut by reason of the slot 12 communicating with the socket 9, and the binding action had between the fiat side of the key and the nut tends to bind the same together, and thereby prevent any lateral turning movement of either the nut or the cap-plate one upon the other. After the key has been set in place the lower projecting end 19 thereof is bent up alongside the enlargement, as shown in Fig. 2, either inward against the under face or outward and against the outer face thereof. Should it be desired to remove the device, the bent end of the key is straightened out and the key may be drawn out of the slot by the aid of some implement engaged with the notch 18, formed in the upper end of the key, and the cap-plate is free to be removed from the nut and bolt, after which the nut maybe removed as usual.
In Fig. 1 the cap-plate'is shown as having a lateral base extension 20, which fits over the similar portion of the fish-plate and the flange of the rail and is provided with suitable notches 21 to accommodate the trackfastenings.
The cap-plate as shown in Fig. 5 has not the base extension, but is provided throughout the entire length of its upper and lower longitudinal edges and projecting from its fiat face with ribs or flanges 22. These flan ges are adapted to embrace the upper and lower edges, respectively, of a fish-plate which does not have the base extension, as in Fig. 1. When the cap-plate has been locked by the wedge-shaped key, the flanges are forced over the edges of the fish-plate, and the cap-plate is thereby held firmly against being accidentally turned.
Changes in the form, proportion, size, and
the minor details of construction within thescope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.
Having thus described the invention, what is claimed is 1. In a nut-lock, the combination with a bolt and the nut thereof, of a cap-plate provided with a socket adapted to receive the nut, an opening communicating with the socket and from the opposite side of the plate and adapted to receive the threaded end of the bolt, a'slot intersecting the opening, and a key adapted to be inserted in the slot and engage the threads of the bolt,'substantially as and for the purpose set forth.
2. In a nut-lock, the combination with a bolt and the nut thereof, of a cap-plate provided with a socket adapted to receive the nut, an opening communicating with the socket and adapted to receive the threaded end of the bolt, a slot intersecting the opening and communicating with the socket, and a wedge-shaped key adapted to be inserted in the slot and be wedged into engagement with the threads of the bolt,and with the outer face of the nut, substantially as and for the purpose set forth.
